Sorry for response to this email but I do not have earlier posts. If you want RSA decryption routine then you may try to extract from OpenSSL some BIGNUM files, probably: bn_add.c bn_asm.c (probably may be removed - depend on your platform) bn_ctx.c bn_div.c bn_exp.c bn_gcd.c bn_lcl.h bn_lib.c bn_mod.c bn_mont.c bn_mul.c bn_recp.c bn_shift.c bn_sqr.c bn_word.c cryptlib.h and compile this to library format. Of course some modification will be needed. With BN library you need only RSA decryption routine which you can borrow from file: rsa_eay.c Depending on decryption scheme you may need RSA_eay_public_decrypt() or RSA_eay_private_decrypt(). If you will need RSA_eay_public_decrypt() some BN files needed for Montgomery method may are not required (bn_mont.c). The most complicated part is to properly define header files depending on you platform architecture (8bit/16bit/32bit).
